Otherwise I agree with Meglobob to allow players to select nations, and think first come first served is okay, because many nations have similar versions.

If not all nations are taken, I think it's best to leave out the ones not selected. If only 30 or so want to play, we might consider have each player control two nations instead of one!

Right now I'm leaning to announcing a sign up time(to be a bit more fair to people who don't monitor the forums 24x7) in advance and simply start letting people pick during that time.
